| 摘 要： | 通过测定杨树溃疡病毒素粗提物处理的6个杨树品种枝条的叶片电导率、脯氨酸含量、多酚氧化酶和过氧化物酶的活性,研究了溃疡菌毒素的致病性及不同杨树品种的抗溃疡病的性能。表明这4个指标均能很好地反映杨树不同品种对溃疡菌的抗病性。

| Abstract: | The pathogenicity of Dothiorella gregaria toxin and canker resistance of different Populus varieties was studied by examining the leaf electronic conductivity, the content of leaf proline, leaf peroxidase and leaf polypheneoloxidase activities of Populus branches treated with rough Dothiorella gregaria toxin. The results showed that these four indexes could reflect different varieties'resistance to Dothiorella gregaria. |
